Initial Configuration of the Control Domain

Initially, all system resources are allocated to the control domain. To allow the creation of other logical domains, you must release some of these resources.

Set Up the Control Domain

This procedure contains examples of resources to set for your control domain. These numbers are examples only, and the values used might not be appropriate for your control domain.

1. Determine whether you have cryptographic devices in the control domain.

   primary# ldm list -o crypto primary

2. Assign cryptographic resources to the control domain.

   The following example would assign one cryptographic resource to the control domain, primary. This leaves the remainder of the cryptographic resources available to a guest domain.

   primary# ldm set-mau 1 primary

3. Assign virtual CPUs to the control domain.

   For example, the following command would assign 4 virtual CPUs to the control domain, primary. This leaves the remainder of the virtual CPUs available to a guest domain.

   primary# ldm set-vcpu 4 primary

4. Assign memory to the control domain.

   For example, the following command would assign 4 gigabytes of memory to the control domain, primary. This leaves the remainder of the memory available to a guest domain.

   primary# ldm set-memory 4G primary

5. Add a logical domain machine configuration to the service processor (SP).

   For example, the following command would add a configuration called initial.

   primary# ldm add-config initial

6. Verify that the configuration is ready to be used at the next reboot.

   primary# ldm list-config factory-default initial [next poweron]

   This list subcommand shows the initial configuration set will be used once you powercycle.
